ABB DAI04 is an evidence-bounded eight-channel low-level voltage and temperature input module. ABB identifies DAI04 as an eight-channel analog input module for low-level voltage, resistance, Pt100 and multiple thermocouple types with 16-bit conversion.
- Channels: 8 analog inputs
- Conversion: 16 bit
- Voltage ranges: +/-19, 38, 76, 154 or 308 mV
- Resistance: 0-1000 ohm
System role: DAI04 acquires low-level voltage, resistance-temperature and thermocouple signals in the legacy Freelance rack. Only facts stated by the cited ABB official sources are published; sibling, predecessor and successor data are not transferred. Architecture boundary: The official certificate lists selectable millivolt and 0-1000 ohm ranges plus Pt100 and thermocouple B, R, S, E, K, J, L, N, T and U support. Exact revision, firmware, host, connector and field-wiring details must be checked against the physical unit and approved project documentation. For maintenance, replacement or migration work, verify the complete nameplate, companion hardware, wiring, configuration and commissioning procedure before returning equipment to service.
Important Notice: Verify DAI04, channel sensor type, compensation, configured range and wiring before use.

Confirm the physical nameplate, current ABB documents, and host-system requirements before installation or replacement.
Installed-base maintenanceSupports evidence-led identification and replacement planning for ABB DAI04.
Freelance rack documentationProvides a source-traceable boundary for the documented controller, I/O or link-module role.
Commissioning reviewGuides identity, companion-hardware, cable, wiring and controlled functional checks before return to service.
Migration assessmentSeparates exact-model facts from sibling modules, later remote I/O and modern controller platforms.
Read and follow the exact ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and Freelance rack configuration.
1Verify DAI04, channel sensor type, compensation, configured range and wiring before use.
2Sensor type, range, compensation and wiring must match the exact configured channel; do not transfer DAI01/03/05 current-input data.
3De-energize the rack and follow the site's approved electrical and process-safety procedure before disturbing hardware or wiring.
4Back up Freelance configuration and controller data before replacement or migration work.
5Verify every rack slot, companion module, system cable, connector, termination and power source from approved drawings.
6Do not copy electrical, communication, mechanical or lifecycle values from a related model, suffix or successor.
7Perform a documented functional test and confirm diagnostics, alarms and configured fail-state behavior after work.
8Origin, HS code, dimensions and logistics weight remain unpublished without exact ABB model-level evidence.
